Dr. Manami Yamaguchi, Your Lake Oswego Dentist

Believing that dentistry is a healing profession, Dr. Manami Yamaguchi makes for a different kind of dentist. As a gatekeeper of health, she runs her practice on three core values: professionalism, attentiveness, and quality. Her office practices with the belief that there is a direct connection between dental care and overall health.

After working in a corporate dentistry setting for four years and learning basic dentistry skills, she worked in a private practice in Lake Oswego. This is where she learned to take care of the community with a more comprehensive focus and where she was given the opportunity to own her own practice. Being the practice owner means being able to say “yes” or “no” to many small yet important things when caring for her patients. It also gives her the freedom to make and implement decisions that improve both her practice and patient care.

As a big sister, she organically grew into the role of a caretaker and educator, traits she shows in her practice today. She grew up in the culture-rich cities of Kyoto and Osaka, in Japan, where art is considered in life’s many stages. She came to the U.S. to earn her BA in biology from Portland State University and her DMD from Oregon Health Sciences University. She continues to further her education with postdoctoral advanced training. To her, dentistry is a wonderful profession that introduces her to many great people, places, and ideas.

Even though she’s passionate about resting, Dr. Yamaguchi keeps busy with three rescued dogs and hiking with friends and her husband around Oregon and Washington. If you ever want to really get on her good side, she is a big fan of razor clam digging and loves it with a bit of Japanese sake.
